[WIP] Lifetime just does not work

[tyb0807]

Made quite some changes everywhere and it still doesn't compile

error[E0195]: lifetime parameters or bounds on method `search` do not match the trait declaration

    = note: due to object lifetime defaults, `Box<dyn SegmentSearchable + Send + Sync>` actually means `Box<(dyn SegmentSearchable + Send + Sync + 'static)>`
